One of the great things about the Role Tailored Client is it's intuivity. People who have never worked with NAV can handle the client perfectly.
As I was going through some issues with an enduser two weeks ago this became clear to me again.
You might know that the RTC always starts with an embeded list page before going to the card page.
Now I always used to doubleclick the mouse or clicked CTRL+SHIFT+E. Now this used pressed Enter and the card opened.
